Title: Baling press with blades rotating within vertical shaft - has extremities of blades curved to eliminate jamming of precompressed material between themselves and walls of column
Inventor: STEINBUECHEL DIETER
IPC: B30B9/30
Filed: 1992-07-14
Abstract: A horizontally working press incorporates a slider in the square-section vertical hollow column (3) set up on the entrance to the compression chamber.

The ends (13) of the blades are bent in a direction opposite to the rotation, leaving sufficient space between them and the walls of the column to prevent jamming. In the wall of the column (3) there is an optical sensor (16), e.g. a light barrier, which detects an arrival of a precompressed material of the preselected thickness. The signal from the sensor is passed to a controller of the press. ADVANTAGE - Throughout capacity of press is increased by precompression of fibrous material.
Patent DE-4224784-A1 (DE)
Title: Operating light barrier, gratings or screens e.g. for protecting machine operator - limiting coded light pulse transmissions to specific time-frame, and enabling receiver to exclude external light and its harmonics
Inventor: JAGST JUERGEN MANFRED
IPC: G01V8/12
Filed: 1992-07-27
Abstract: The method of operating a protective light source, light barrier or light curtain (5), which projects cooled light pulses to a receiver (E) at regular intervals, involves controlling the successive transmissions such that they occur within a time frame of duration (ti). The coded pulses (C0,C1) are wholly contained within the time intervals (t2,t3) for independent identification at the receiver (E) which is activated only during the time frame (t1). Interference from external sources, e.g. welders, strobes, etc., is known to occur at fundamental frequencies less than 1/t1 and can therefore affect only the pulse (C0) or (C1) leaving one pulse clearly identifiable. By suitable choice of the intervals (A,B) within the frame (t1) the possibility of interference harmonic affecting both pulses (C0,C1) is also eliminated. ADVANTAGE - Ensures light-operated safety devices e.g. for protection of machine operators are not adversely affected by light from adjoining sources.

Title: Colour printing head - uses single type of fluorescent material for light points formed by controlled electron emission and colour filters for light
Inventor: SHIMIZU YUKIHIKO
IPC: B41J2/525
Filed: 1992-09-30
Abstract: The colour printing unit, for a colour video printer or colour printer and the like, has an electron emitting electrode, anodes with the light emitting points through the electrons from the electrode, and control electrodes to control the electron flow from the electrode so that the light point is formed by a fluorescent with an emission spectrum of one, two or more colours. A colour filter determines the colour of the light emitted from the light point. Pref. a number of light emitting blocks are on a substrate (1), against each other in a sub-scanningline, where each block colour (R) has an anode conductor (2) along the inner surface of the substrate (1) parallel to a main scanning line. Light points (5) of the same fluorescent (4) of the same assembly are in the same position and take deposits on the anode conductors (2) on the main scanning line. The light points (5) are positioned against each other between the colour light blocks (R). Cathodes (14) emit electrons, with control electrodes (7, 10) for the emitted electrons. A housing is sealed against the inner surface of the surface of the substrate (1) to shroud the control electrodes (7, 10) and cathodes (14). A number of colour filters give colour discrimination in front of the corresponding colour light blocks (R) at an outer surface of the substrate (1). A number of anode conductors are equidistant along the sub-scanner so that the light points (5) are angled at the light blocks (R) against each other on the main scanning line. ADVANTAGE - The colour printing is effected with a single type of fluorescent material. The accuracy of the light points is increased to give high-quality printing.
